Abstract: 528,961. Controlling aircraft. CHOWN, W. R., and HILLS & SONS, Ltd., F. Aug. 17, 1938, No. 24231. [Class 4] [Also in Group XXXVII] A target aeroplane is controlled by means of a band of material having slots or perforations which moves over electric contacts to open or close electric circuits of actuating mechanism for the rudder and elevator. The aeroplane is driven by a petrol motor and has a time switch for releasing a parachute to minimize damage when landing. A motor 18, Fig. 6, continuously driven by an accumulator near the front of the aircraft drives through worm gear 42, 43 a drum 37, and, by means of a chain 44 a spool 52, so as to draw a strip of paper from a spool 26 over a series of contacts, not shown. A carriage 38 supports guide rollers 34, 36 and also a metal drum 29 through which circuits are completed whenever a slot in the 'paper strip is between the drum and one of the contacts. The elevator and rudder are each separately controlled by a device comprising an electromotor 52, Fig. 9, adapted to drive a screwed shaft 59 to traverse a block 60 connected to a crosshead 63 by which the rudder or elevator is moved through a rod 64. The paper strip causes energization of either of two electromagnets for moving a normally centralized commutator switch to start the motor in one or other direction, the block 60 actuating limit switches to prevent overrunning. There is also a centralizing circuit to centre the block 60. A time switch actuates a solenoid 14, Fig. 1, to withdraw a bolt for releasing a parachute container 12 as described in Specification 527,693. According to the Provisional Specification the parachute may be released whenever a network of wires is broken also as described in Specification 527,693 or it may be released by a barometric device when a pre-determined height is attained.

Title: Fluorescent compositions
Inventor: GAUNT THOMAS NORMAN
IPC: C09K11/06
Filed: 1955-08-26
Abstract: A modification of the method of making a fluorescent composition as set out in the parent Specification comprises the steps of dissolving an alkyd resin or a mixture of such resins in an aqueous alkaline medium, adding to the solution an aqueous solution of a precipitant for the resin or resins, dissolving or dispersing in the aqueous suspension of precipitate a dyestuff which has fluorescent properties in the concentration employed and separating the dyed precipitate. The examples described and the materials used are the same as set out in the parent Specification except that instead of dissolving or dispersing the dyestuff in the aqueous alkaline solution of the resin or resins, the latter is first precipitated from the solution by an aqueous solution of a precipitant and a solution or suspension of the dye added afterwards.  In an additional example, "Bedesol 76" (Registered Trade Mark) is used as the alkyd resin and Rhodamine B as the dyestuff.  In a further example, an ink is made by dispersing a composition made in accordance with the invention in a varnish consisting of "Paralac 21" (Registered Trade Mark), dibutyl phthalate, to which Rhodamine B and Rhodamine 6G are added, and triethanolamine.

Title: Improvements in or relating to thermally operated electrical switches
IPC: H01H37/40
Filed: 1931-09-02
Abstract: 385,668. Thermal switches. PAYNE, M., 50, Hook Road, Surbiton, Surrey, and BRITISH THERMOSTAT CO., Ltd., Windmill Road, Sunbury, Middlesex. Sept. 2, 1931, No. 24661. [Class 38 (v).] In a thermally-operated electric switch of a kind in which the movements of the switch member are produced by the expansion of a fluid in opposition to an adjustable spring, the lever 18 or other element transmitting motion from the fluid cylinder 5 to the switch 17, is pressed against a pin 20 on the operating member 9 by a spring 21 so as to avoid lost motion while securing resilient transmission in the event of sudden movement. The flanged end of the member 9 is connected to a metallic bellows 4, the space between which and the cylinder forms a chamber containing volatile liquid. One end of the bellows is sealed to the open end of the cylinder 5. When the pressure in the chamber 5 due to a rising temperature moves the part 9 sufficiently to the right against the opposition of the helical spring 8, the lever 18, which is pivoted to the casing at 19, operates a tilting mercury switch 17 so as to interrupt the connection between the wires leading to the two parts of the switch. The connection between the end of the lever 18 and the member 9 comprises a transverse pin 20 and a light spring 21 which yields to excessive pressure to prevent overloading of the lever 18. The resistance of the spring 8 can be adjusted from the outside of the casing by a small handwheel 15 mounted on the end of a screw 14 which engages the abutment 12 of the spring. The casing 1 is divided by a partition 28 into a main chamber a which contains the lever and the mercury switch, and a smaller chamber b containing the connecting wires by which current is led into the instrument to the terminals 29. The chamber b may communicate with an opening 30 at the top of an opening 32 in the base of the casing.

Abstract: 259,951. Rheinische Metallwaaren und Maschinenfabrik. Oct. 17, 1925, [Convention date]. Mountings.-In gun-training gear, reaction upon the driving-means is prevented by the use of gearing comprising a worm and wheel arranged in parallel with the main driving gearing between the motor or the band driving the apparatus and tile driven member. The gun carriage b carries a toothed ring c engaged bv a spur wheel d on a shaft e which carries a wheel f, driven by a wheel h on the driving shaft i, and a worm wheel g engaged by a worm q on a shaft o driven by multiplying gearing m, n from the shaft i. In order to ensure that the worm q maintains such close engagement with the worm wheel g as effectively to prevent reaction on the shaft i when the driven member reverses, a spring coupling p, or a slipping frictional gear tending to cause over-driving of the worm, is inserted in the shaft o and a lost motion coupling k in the shaft i. Overrunning of the driven member brings the worm wheel against the opposite face of the worm and locks the parts before the lost motion in the coupling has been taken up. The coupling k is preferably such as to release automatically and transmit no power when the speed or the torque exceeds certain limits. The spring and lost-motion couplings may be interchanged. Specification 276,847 is referred to.
